PA612 ESD vs PA612 GF30

Polymer · PA612 grade comparison

PA612 ESD and PA612 GF30 are two grades of the same polymer grade, PA612: ESD (ESD / antistatic) versus GF30 (30 % glass-fibre reinforced). The chemistry is identical, so every difference below comes from the condition. PA612 GF30 is the stronger of the two: yield strength 58 MPa (8.41 ksi) against 53 MPa (7.69 ksi) for PA612 ESD, about 9% more; tensile strength follows at 155 MPa (22.5 ksi) vs 55 MPa (7.98 ksi). In exchange, PA612 ESD is the more ductile: elongation 25% versus 3.5% for PA612 GF30. PA612 ESD is lighter (1.1 g/cm³ vs 1.31 g/cm³ for PA612 GF30) and PA612 GF30 is stiffer (8.8 GPa vs 2.4 GPa). On the shop floor, PA612 ESD machines more easily (good vs fair) and PA612 GF30 welds better (good vs fair).

PA612 ESDChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

PA612 GF30Choose it when strength drives the design, or when the part sees heat.

PA612 ESD vs PA612 GF30 — frequently asked

Is PA612 GF30 stronger than PA612 ESD?

Yes. PA612 GF30 has a typical yield strength of 58 MPa (8.41 ksi) against 53 MPa (7.69 ksi) for PA612 ESD — about 9% more. Tensile strength is 155 MPa (22.5 ksi) vs 55 MPa (7.98 ksi).

Which grade does FabDigit quote by default, ESD or GF30?

NAT-DAM is the default PA612 condition in the FabDigit quote flow (neither ESD nor GF30). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, PA612 ESD or PA612 GF30?

PA612 ESD. Its machinability rates good (65/100) against fair (45/100) for PA612 GF30; for welding the order is PA612 GF30 first (good, 55/100) then PA612 ESD (fair, 40/100).
